To all whom t may concern.'

Be it known that l, ALBIN OLssoN, a citizen of the United States,residing at Renton, in the county of King and State of Washington, haveinvented a new and useful Log- Car, of which the following is aspecification.

This invention relates to improvements in log cars and more particularlyto a log car of the class known as telescoping cars.

An object of the present invention is to provide a longitudinallyextensible and centractible car with means secured thereto whereby anair brake of the ordinary type may be installed upon the car.

A further object of the invention is to provide a longitudinallyextensible and conti'actible car with an air brake of the crdinary typesecured thereto and adjustable means whereby the air brake is adapted tooperably engage the trucks regardless of the distance apart of the same.

With the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

ln the drawings accompanying this specification and forming a partthereof, the preferable form of my invention is illustrated,' in whichFigure 1 is a side view in elevation of my improved car. Fig. 2 is abottom plan view thereof with the trucks removed. Fig. 8 is a detailview of the main beam or center sill of the car. Fig. 4 is a detail Viewin cross section showing the interlocking main beams.

Referring to the drawings in which similar reference numerals designatecorrespond- Ving parts throughout the several views, 1 are Speccaton ofLetters Patent.

In order that the car trucks and holsters supported thereby may bepositioned at varying distances apart in order to accommodate logs ofdiferent lengths, the telescoping or interlocking main beams 5 and 6 areprovided, a cross sectional view of which is illustrated in Fig. 3 ofthe drawings. rlhe main beams may be interlocked as shown in Fig. 4, inwhich the upper beam 6 is provided with downwardly extending tonguesinterlocking with upstanding tongues of the beam 5. rEhe main beams orcenter sills 5 and 6 are rigidly secured to the holsters 4 and areadapted to hold the same in spaced relation, it being noted that thesaid beams extend beyond the bolsters and are provided at their outerextremities with suitable car coupling members 7. lThe main beams 5 and6 are preferably formed of metal and are provided with a number of slotsor apertures 8 extending therethrough and which apertures are adapted toreceive suitable holding bolts or pins 9 therein, there being suitablecotter pins 10 or other equivalent means secured to the outerextremities of the bolts to prevent the accidental displacement thereof.

In order that both of the trucks may be provided with automatic brakesoperated from a common brake cylinder, mechanism as illustrated in Fig.2 is employed and this mechanism comprises an air brake cylinder 11which is operably connected to the floating lever 12 to one extremity ofwhich is secured the reach rod 13 which extends to the forward truck andis adapted to operatively engage the brake rigging positioned thereon. Asuitable hand brake operating mechanism 14 is pivotally secured to theremote end of said floating lever.

Pivotally secured to the end of the center beam 6 which supports thecylinder 11 is a transverse lever 15 the one extremity of which isforked as at 16 and is adapted to engage one of a plurality of apertures17 f floating lever 12 with the fulcrumed lever tracted the pin 21 whichextends through the forked portion of the fulcrumed lever 15 and engagesone of the apertures 17 is withdrawn, which allows the reach rod 18v totake up a new position with respect to the lever 15 after which the pin21 is reinserted in place and the brakes of the two trucksl will then beoperatively connected to the brake operating mechanism.

Rigidly secured to the center beam 5 is the air pipe 22, the same beingprovided with a number of flexible hose couplings 23 positioned atvarious intervals therealong and which flexible hose couplings areadapted to engage a single hose coupling 24 which is secured to the airpipe 25 positioned upon and secured to the main beam 6. Each of the hosecouplings 23 are provided with suitable shut-off valves 26 so that whena particular hose coupling is not in use, it may be closed to preventthe escapement Vof air therefrom. The iiexible hose couplings are of thetype such as are used at the extremities of the car as shown at 27.

From the foregoing it will be apparent that 1 have provided a car whichis longitudinally extensible and contractible and at the same time haveprovided an air brake operating mechanism secured thereto and whichmechanism is adapted to operate the brakes of the forward and reartrucks regardless the distance the same are located apart. The bolstersof the cars are used to directly support the logs or other material ofconsiderable length and limited cross section and due to theconstruction above outlined, the car will be comparatively light inweight which is of importance in the mountainous logging districts wherethe empty cars are drawn back to receive a new consignment of logsthereon. Furthermore the conditions met in this service require thatsubstantial brakes be provided which renders it almost absolutelynecessary that air brakes be used. By the arrangement of parts as 1 haveoutlined, the single and ordinary Vair brake unit may be secured to eachof the cars and is adapted to adjustably and operatively engage thebrake rigging provided upon each of the trucks. Furthermore theproviding of a number of hose couplings at various intervals along thedivided air pipe which extends along the car allows the said pipe toalso take up the differences in length between the two trucks.

The service for which the cars are to be used makes it necessary thatthe distance between the two trucks of each and every car may beadjusted and in the construction hereinbefore described this is readilytaken cured to the said trucks, and air brake mechanism rigidly securedtol one of the said beams and adapted to adjustably and operativelyengage the said truck brake rigging.

2. A longitudinally extensible and contractible log car comprisingtrucks with brake rigging thereon and bolsters pivotally securedthereto, main beams rigidly secured to said bolsters and insertible onewithin the other, said beams provided with transverse aperturesextending therethrough adapted to aline and receive holding meanstherein, said holding means adapted to hold said beams in` fixedrelation, andan air brake operating mechanism rigidly secured to one ofthe said main beams and operatively and adjustably engaging the truckbrake rigging.

3. A log car comprising trucks with brake rigging secured thereto,bolsters pivotally secured to the said trucks, a main beam rigidlysecured to one of the said bolsters and provided with a plurality ofapertures extending transversely therethrough, a hollow main beamrigidly secured to the other of said bolsters and provided with aplurality of apertures extending transversely therethrough and aliningwith the apertures in the first mentioned main beam,'said main beamsinsertible one within the other, means insertible` into the alined beamapertures adapted to hold the same in xed relation, an air brakeoperating mechanism secured to the said hollow beam and adapted toengage the truck brake rigging there adjacent, and a reach rodoperatively connected to the brake rigging of the other truck andprovided with a plurality of apertures extending therethrough, saidreach rod adjustably engaging the said air brake operating mechanism,air pipes rigidly secured. to thesaid telescoping beams, one of the saidair pipes provided with a plurality of hose couplings arranged atintervals therealong, the other of said air pipes provided with a hosecoupling adapted to engage the hose couplings of the other air pipe.

4. In a longitudinally extensible and contractible log car, thecombination of trucks with brake rigging thereon, bolsters pivotallysecured thereto, metallic main beams rigidly secured to said bolstersand insertible one within the other, an air brake cylinder rigidlysecured to one of the main beams and operatively engaging'the brakerigging of the adjacent truck, adjustable means en- LGV/41,812 v gagingthe brake rigging of the other truck and adjustably engaging the saidother truck operating mechanism, air pipes rigidly secured to the saidmain beams, one of said air pipes provided With hose couplings arrangedat intervals therealong, a single hose coupling secured to the other ofsaid air pipes and adapted to engage one of the said plurality of hosecouplings of the other of the air pipes, and means for holding the said10 beams in fixed adjusted relation.

In testimony that I claim the foregoing as my own, I have hereto afliXedmy signature in the presence of tWo Witnesses.
